TSUNAMI

  tsunami (from Japanese: 津波, "harbour wave";[1] English pronunciation: /suːˈnɑːmi/soo-NAH-mee[2] or /tsuːˈnɑːmi/[3]), sometimes incorrectly referred to as a tidal wave,[4][5][6]also known as a seismic sea wave, is a series of waves in a water body caused by the displacement of a large volume of water, generally in an ocean or a large lake. Earthquakes, volcanic eruptions and other underwater explosions (including detonations of underwater nuclear devices), landslides, glacier calvings, meteorite impacts and other disturbances above or below water all have the potential to generate a tsunami.[7] Unlike normal ocean waves, which are generated by wind, or tides, which are generated by the gravitational pull of the Moon and the Sun, a tsunami is generated by the displacement of water.
